THING IECHANIBM AN PROCESS OF nnnnroacmd MATERIAL ron axons.

Application med october 5, 1925. serial mt'eofna'lV Our invention relates to the general art of mechanism adapted to apply reenforcing tape to any articles and particularly relates to improved mechanism for applying tape in other than straight lines, especially to leather vamps, tips and the other parts of Y shoe up rs which require reenforcing.

It is t e object of our invention to provide im rovedl mechanism'operating in timed re l0 lation to work feeding mechanism such as a' sewing machine operated without the needle, which will automatically feed suitable tapi 'material onto the work as it is fed through the machine. j

It is further our object'to provide cutting means operating in timed relation to the tape feeding mechanism whidh will snip with little cuts extending into the tape from the side, either one or both edges of the tape -20 so that the tape will lie flat when applied in other than straight lines onto any given work.

It is 'our object* to provide means to inhibit the cutting means at thewill of an operator. l

It is an object of our improved mechanism to provide a guard plate which will-prevent j the tape sticking to andbein carried around on the tape feed roller. inally it 3 0 is our object to provide an improved mechanism operable under the presser foot and inner walkingi foot of a sewing machine which will 'rovide from under the work a feeding mec anism operating in time with i the snipping knives and the presser and walking foot.

The particular d-iliiculties'which have been encountered in connection with the use of the novel taping machine as disclosed in co-l i W pending application Serial No."662,134, filed September 11, 1923, as utilized for carrying lthe machine which is mounted on a table 2 out the process of reenforcing shoe vamps described in Patent No. 1,556.124, issued Oct.' 6, 1925, are three. One diliiculty has been the tape being fed over a rotary feed has sometimes caught in the rotating element and been carried around with it., Our novel guard plate prevents this diiculty. Another diiculty has been that the" regular sewing machine under feed plate is diiiicult to install-in connection with. our improved mechanism lfilip/feeding and snipping the tape. Ournov'el underneath feed foot overcomes the mechanical difficulties involved in. adapting the regular under feed plate of a .sewing machine with our improved mechanism r feeding and snipping the tape` Finally the greatestl improvement in our structure has been in the provision of a reciprocating cutter which snips the tape from a side edge so that the tape will always lie flat even when used on very acute bends in the work.

The side edge cutting mechanism enables the tape to be applied to the curve of a shoe vamp without the necessity of having to use scissors to snip the work afterward, which saves a great deal of hand labor with! the consequent reduction in the cost of the shoes and further improved quality of vthe work y done.

In combination with our mechanism we have provided a simple means of accomplishing an improved process of reenforcing shoes' and leather which should be considered the '1liu most essential ob'ect of our invention,

`Referring to t e drawings`in which wehave illustrated our preferred mechanism Fi re lis a side elevation of 'a sewing machine with the addition of our preferred improved mechanism.

Figure 8 is a Fi re 5.

enerally lindicated at 1 is the frame of detail along'the lines 8-8 in at which the operator sits. The mechanism is illustrated as being supplied with driving power from a motor 3. The shaft 4 is driven by a belt and pulley 5 and 6 respectively, and as shown in Figure 5 the shaft drives an eccentric stud? to which is connected the link'8 and the link is ivoted on a pin 9 held fast in the arm 10. 10v has a nose'll adapted to be engaged by a lift 12 and an arm 13 is pivoted on the-arm 10. The arm 13 engages by 'clamping overthe presser foot rod 14. A spring 15- on the presser foot rod is engaged by the arm 13 '110 Figure 3 is an end elevation of a portion i i 6 is a detail elevation showing the presserv foot loo l and also by the casingrat the top of the machine through which casing is slidably set the end of the rod 14. The presser footfrod is thus operated so as to be lifted, with the spring tensioned to move the foot to depressed position. The presser foot 16 is disposed on the end of the presser foot rod and is a slotted member. The walking foot,

which is shown at 17, rests in the slot of the presser foot and is mounted on a rod 18 which is pivoted as indicated at 19 to a link 20. The link 20 is also connected to the pivot of the arm 13 as indicated at 21.

The o eration of the walking foot and the presser oot is as follows: The eccentric stud t at the top of the machine revolves thereby rocking the arm 10 and with it the link 20, so that the end of the link which is pivoted to the arm 18 is moved downwardly. When the foot 17 contacts with the underneath feed foot, which will be described hereinafter, the

` guide roller 32 a 'so rotatab feeding foot is oy with the rotatably 4pivot at. 19 will permit the foot 17 to travel `along with the underneath feed foot. At the moment of contact of the walking foot with Vthe underneath feed foot the pivot at 19 can 'no longer move downwardly so that the arm finger 24 mounted on the shaft22 (Figures 3, 6 and 7) is enclosed in an internal cam portion 25 on an underneath feed foot 26. Thismember is pivoted as shown at 27 to a stationaryv link 28. The upper end 29 of the member is preferabl roughened and the limit of movement o the roughened end is upward enough to contact with the walking foot 17 at which point the internal cam reaches a corner so that upward movement is limited and the two feet together advance the work and the tape disposed on the work. .This cycle of movement 1s repeated as the work and the tape p are fed through the,

mechanism.

.The taping supply may be as indicated tape formed into a roll 30 on a mounted spool 31. Feeding from the spool the ta e passes referablyI to a y mounted and supported 'by a bracket 33 in which the roller is journaled. The adhesive surface of the tape is on the outer side of the supply so thatv an unadhesive face passes .over the roller 32. Another roller 34 which ma as 1n shown 'be a rotatable shaft is journale brackets 35 and driven by a pulley 86, driven by a belt` 3 7, which is engaged about tthe shaft 34. The

. used to make a clean cut in an a pulley 38 mounted on the presser foot shaft 4. A guard late 39 with trunnion-like journals at the si es is loosely mounted on tape is Withdrawn from the supply by-the rotation of the shaft 34 to which the adhesive surface of the ta adheres sufficiently to exert a suitable wit drawing tension which unrolls the ta e. The tape passes over the roller 34 in t e posi tion indicated in dotted lines in Figure 8 and the guard plate as will be obvious prevents the tape from sticking to the `roller 34 and wrappin about it.

From the eed roller the ta uide'rollers 40 throu h the eating chamer 41 in which the a esive is warmed 'ust enough to stick tightly \to the' Work. he tape is drawn with its adhesive face up to the feedin feet, being preferably tensioned through s itted guides 42 just before it passes to thefeeding feet.

The cutting device with which nterspaced slits are snipped in a side ed e of the tape is constructed as follows n the shaft 22 (Figures 3 and 4) a crank 43 is eccentrically mounted. The end of the crank is pivoted to a cross link 44 which is pivoted in a fixed link as at 45. l The other end of the cross link 44 is pivoted to the base of a plunger rod 46; as the shaft 22 turns the plunger rod is oscillated up and down. The oscillating cutter knife 47 which is vertically e passes over mounted so as to move across the path of the I tape is secured at its base to a rod 48 which is tensioned with a sprin A49 toward a down posit-ion. The lower en of the rod 48 and the upper end of the plunger rod 46, are i11- 'terspaced so that a clutch member 50, pivoted to a shifting rod 51, which is pivoted to a treadle member 52 is disposed in position vto be moved by an yoperators knee into engaged position.l It is referable to have the clutch member out o en gement during the regular yoperation of tlg; taping mechanism which may be provided by a sprin 53 extendin from the frame of the mac ine and tensionedto pull the treadle connectinig link 54 to the left as shown in Figure 4.

`IVhile in the foregoing disclosure we have onlydescribed one mechanism for snipping a side edge of thetape, it will be readily understood that modifications in the type of knife used'by which slits may be made in the tape in any desired positions will readily occur to those skilled in the art. Our invention consists primarily in the idea of.

before -its application to slitting the ta work, and also providing suitable mechanism with which an operator ma slit an vedge of the tape during any pre erred in- .iso

mames tervals while the tape is being applied.
